SANITARY PAD.

Application filed September 16, 1923. Serial No. 135,978.

This invention relates to sanitaryl pads for refractors such as used by eye examiners' and the like. j

One object of the invention is to design a sanitary pad of simple and cheap construc-p tion, which can be readily placed on or removed from the machine, and which is not affected by the adjustment thereof,

A further object is to provide a sanitary pad of iiexible absorbent material, and provide means for securing it in position.

)Vith the above and other objects inrview, the present invention consists in the produc-y tion of a sanitary pad hereinafter fully described, illustrated in the accompanying drawing and particularly pointed out in the appended claims, it being understopdthat changes may be made in the form, size, and proportion without departure from the spirit of the invention.V y

In the drawings. f

Fig. l is a -front view showing my'improved'sanitary pad. j

' Fig. 2 is an edge view thereof.` 'p Fig. 3 is afront View ofa refractor showing the sanitary pad in lplace thereon, the` lens discs of the refractor being shown in two different positions.

Fig.Y 4 is a top plan viewthereof. In the testing of eyes where the patient rests the face or portions thereof against any piece or part of the apparatus, it isr essential from a sanitary' standpoint, that these parts be covered with asuitable covering or pad which canbe removedand renewed for each patient in order that the operation be entirely sanitary, and where the Vmachine or part to which it is attached is adjustable, the pad must be designed to accommodate itself to said adjustments, and

Vstill cover the parts as above described, and

I have therefore designed a pad vwhich incorporates this feature, and which is easily replaced and attached.

Referring now to the drawing, the numera 5 indicates the frame of a conventional refractor such as used by eye examiners, and to which the sanitary pad 6 is adapted to be applied, these refractors are operable by the eye examiner, and are provided with anupstanding pin 7 which is a part thereof, the

Aand placedy in position.

over the refractor, andY is securedon the pin 65 thereof.

Spaced apart elongated Vslotted openingsV l0 and l0 are providedin the face of the pad, so thatfas the distance between thevcenl ters of the lensesfll is changed by adjustment, the pad will not obstruct or cover said lenses,the length of the slotted openings4 being the range of longitudinal,adjustment ofthe refractor lenses; l

From the foregoing description it will be obviousV thatv I have perfected a simple, eco-v nomical and convenient `sanitary pad for refractors, which can ,be quickly removed VJhat'I claim is s Y l. A sanitary absorbent pad formed of iieXible ,material providedwith spaced apart horizontally extending elongated openings,

and a strip projecting-from the upper edge thereof for securing the padv to a refractor frame.

2. A sanitary pad formed of flexible absorbent materialand provided with centrally disposed spaced apart horizontally extending elongated openings, and a strip formed integral 'therewith and vprojecting froinjthe upper edge thereof for securing the pad to a refractor frame. Y Y

3. The combination with the frame of a refractor, of a sanitary pad shaped to cover theQlens frames thereof and provided with spaced apart horizontally extending elongated openings, anda laterally projecting Y strip on the upper edge thereof for securing 4 the pad to thejrefractor frame.

n testimony whereof I affix my signature.
